Collection: BMW 4 Series G23 Convertible (2021–2024)

BMW 4 Series G23 Convertible Carbon Fiber Parts (2021-2024)

The G23 is BMW's current-generation 4 Series convertible, spanning 430i and M440i trims and closely related to the M4 G83 Convertible, as well as the G22 Coupe and G26 Gran Coupe siblings. AeroBon's real and dry carbon fiber trunk spoilers and mirror cover options are molded to match the G23's factory profiles for a clean, track-inspired upgrade.

Choosing the Right Option

OE Style gives a subtle, factory-look trunk profile, while GC Style adds a more pronounced kick for a track-inspired stance. For mirrors, Replacement Style swaps the entire factory mirror cap, Add-On/Overlay styles fit over the existing mirror cap without removal, and MA Style is a wide-fitment overlay compatible across BMW's current G-chassis lineup.

Fitment Clarification

Both trunk spoiler styles are shared with the M4 G83 Convertible, since the G23 and G83 use the same trunk lid profile. The mirror products are shared broadly across BMW's current G-chassis 3/4/5 Series and i4 lineup, since these platforms use matching mirror housings within each style category.
